提出了利用卡尔曼滤波算法以重构结构响应为目标的应变传感器和位移传感器位置优化和数目确定的方法。通过从传感器位置候选群中不断删除对响应重构精度贡献最小的位置，直到最大规则化重构误差方差或者平均规则化重构误差方差等于或者大于预设的阀值，由此来确定位移和应变传感器的数目和优化的位置，并综合利用这两种响应重构关键位置的位移和应变响应。数值算例结果显示，利用优化位置的测量信息重构的响应与数值计算的响应吻合良好，并且综合利用两种信息重构得到的响应比用单种信息重构的结果精度更高。

Here,the optimal design method for integrated sensor systems including both strain and displacement measurement sensors with the objective of possible best reconstruction of structural responses using Kalman filtering algorithm was proposed.The locations were deleted from the candidates under the condition that the deletion caused the minimum reconstruction error until either the normalized maximum reconstruction error variance or the average theoretical one reached the predefined threshold.Then,the numbers and locations of the two types of sensors were determined.A two-dimensional truss structure was presented as a numerical example to investigate the effectiveness and accuracy of the proposed approach.The results indicated that the reconstructed responses are in good agreement with the real ones and the integrated sensor system provides a better reconstruction of structural response than the single-type sensor system does.
